<p>几点说明：</p>
<ul>
<li><p>为了让CSS代码层级关系更加明显，下面代码案例使用的是 Less</p>
</li>
<li><p>如果想清除浏览器默认效果，可以使用 <a target="_blank" rel="noopener" href="https://sourl.cn/MiNzfr">CSS Tools: Reset CSS</a></p>
<p>但是这个可能并不太好，可以参考 <a target="_blank" rel="noopener" href="http://www.zhangxinxu.com/wordpress/?p=758">CSS reset的重新审视 – 避免样式重置</a></p>
